Model : HME-LAMP
1. Summary
There are many RF reduction causes in tunnels. HME-LAMP boosts up the RF signals which weaken in the tunnel and RCX, LCX cables. It provides seamless communication service between a base station and a mobile station (an engineer). It has a built-in Automatic By-Pass function to minimize all kinds of risks in the emergency situations. It amplifies various frequencies from FM band to TRS band to provide a composite Line Repeater Solution.
2. Features & Functions
- -Amplification for each RF signal such as FM Radio (88~108MHz), VHF Station communication (146~174MHz), Fire Communication /Train Protection (440~470MHz), Ground-wave DMB(174~214MHz), TRS(800~900MHz)
- -Appropriate Solution for train environment which has various types of communication, offering compatibility for Digital TRS Repeater & other repeaters
- -Applying for NMS, and Observing & control function at the end of the RCX cable by interlocking with LD
- -Built-in Automatic By-PASS function
